    The spacecraft will be a roughly rectangular three-axis stabilised satellite, weighing approximately 4.1 tonnes at launch (1.7 tonnes dry mass), measuring approx. 2 m x 2 m x 3 m in stowed configuration, with two deployable solar arrays. It will have a power budget of around 3 kW and a large volume (200 Tbits) of science data to be downlinked to Ea...

    The EnVision launch is scheduled for November 2031, with back-up dates in 2032 and 2033. The mission will launch with an Ariane 64 rocket (direct escape). The interplanetary cruise phase will take around 15 months. The Venus orbit insertion will be highly elliptic, and the final science orbit will be reached by means of Aerobraking. The Aerobraking...

    The science data downlink capability is ~200 Tbits using Ka-/X-band comms system with a >2.5 m diameter fixed high-gain antenna.

    The spacecraft orbit will be polar, with a duration of ~92 minutes and an inclination between 87o and 89o. The orbit will be elliptical, with spacecraft altitudes varying between ~220 and 510 km above the surface. The slow rotation rate of Venus leads to a slow build-up of the observation coverage of the planet during the 6 Venus sideral days (~4 E...

    EnVision is an orbital mission to Venus being developed by the European Space Agency (ESA) that is planned to perform high-resolution radar mapping and atmospheric studies.

  4. Jun 10, 2021 · The earliest launch opportunity for Envision is 2031, with other possible options in 2032 and 2033. The spacecraft would take around 15 months to reach the planet, with a further 16 months to achieve orbit circularisation through aerobraking.

  5. EnVision was selected as ESA’s 5 th Medium-class mission in the Agency’s Cosmic Vision plan, targeting a launch in 2031. The mission was adopted in January 2024. The objective of EnVision is to use the observetions of the different parts of the Venus system to studying the planet's history, activity and climate.
